82C89 CMOS Bus Arbiter Datasheet

82C89 CMOS Bus Arbiter

PIN SYMBOL NUMBER TYPE DESCRIPTION VCC GND 20 10 VCC: The +5V Power supply pin. A 0.1F capacitor between pins 10 and 20 is recommended for decoupling. GROUND. S0, S1, S2 1, 18-19 I STATUS INPUT PINS: The status input pins from an 80C86, 80C88 or 8089 processor. The 82C89 decodes these pins to initiate bus request and surrender actions. (See Table 1)..
